Yes, I had a pair years ago.
 I have read that some are aggressive to small finches and some are not and will mix in well in a mixed aviary. I wouldn't risk it myself. They are very pretty birds. 
 After reading that, I wouldn't put them in with zebras, strawberries or other tiny ones. 
 We may have members who have mixed them with success. Check back for more replies later.
